    Automotive machining question…

    Been turning wrenches for 55 years... absolutely do NOT use compression fittings on a vehicle. They work (sort of) in a house because the house (usually) doesn't move or vibrate. If used on a vehicle which vibrates, they will leak. Every time. CutterBill

    floor jack (or other type) recommendation

    Floor jacks are expendable tools. Buy cheap (Harbor Freight is fine.) When it breaks, throw it out and buy another. Bill

    Or just make one. It's not hard... For my Graziano SAG12, piece of 1.5 inch thick mystery aluminum I found in the shop (it cut like 6061.) Some half-inch bolts with bearing bronze caps pressed onto the ends. Works just fine... Bill

    Radial Force on Ball Bearing Via Vice Setup, Type of Vice Recommendation Needed

    I recommend that you look at the bearing manufacturer's engineering manuals. Timken and SKF both have extensive manuals online. All of the testing has already been done and the info is in the manuals. Bill

    Is this Sag 12 worth the price?

    I have a SAG12 which I bought about 10 years ago. Paid $3000 for it but it had been used only for cutting nylon and was carefully maintained. Also came with a good 3-jaw, a drawer full of soft jaws and a well-made collet closer. I really like it; good lathe. Absolutely do NOT buy this lathe...

    Series 1 Bridgeport DRO recomendation

    dropros.com Edit: be wary of the the cheap Chinese DRO's. I have one on my Bridgeport and it actually works quite well. But I can't read the manual... the words are English but the sentence structure is not. :D Bill

    MD who Scrapes like a Pro

    That shop looks like he never makes anything, just spends all day polishing his machines. Wow! Seriously, how does he control the mess? Flying chips, coolant, and cutting oils? Or does he just cut everything dry? Amazing shop. I'm a bit jealous... Bill

    OT Educate me on home AC

    Nope, it's true if you live in a humid climate (like Houston.) A small unit will run for a longer time than a large unit, thereby removing more moisture from the air. The large unit will come on, quickly lower the temperature inside the house and then shut off, but it won't run long enough to...

    Advice for an odd case of stripped holes

    FAA certified A&P mechanic with Inspection Authorization here... My head just exploded. You're going to fix a metric bolt/hole on a French (metric) airplane with an inch-sized tap/drill?

    Air Rivet Guns

    Ohhhhh.... FYI, those aren't "rivet guns." Those are "pneumatic rivet pullers." Rivet guns drive solid rivets against a bucking bar. Bill

    Air Rivet Guns

    Ummm... you do know that rivet guns require oiling, yes? At least daily. Run dry, they won't last long. Bill
